Optical electronics

What is Information?Electronics is concerned with information - its generation (or transformation from one form to another), transmission, storage, processing and reproduction. The information can be generated in "electronic" form in a multitude of ways, from speech, pictures, printing and writing, temperature, pressure, chemical processes, blood flow, heart beats, velocity, vibrations and many other sources. In fact anything that can be measured can be translated, assuming a suitable transducer exists, into electronic information. Information, in whatever form it exists, can itself be quantified and therefore measured. It follows that the rate at which information is transmitted (rate should not be confused with velocity or speed), the amount of information stored, the rates at which it can be processed and reproduced, can all be expressed in precise numerical terms.
